The best, nay, the _only_, environment would be one that handles the source code that MySQL is written in. That's not C#.

Your task is non-trivial. A better approach:
Develop some Stored Functions and Stored Procedures. They would take work with the intervals. You might be better off storing the intervals as two fields -- either DATE or INT. "1/5/2012" is a bad format to use -- it cannot be compared. It would be better to use the format that DATE uses: "2012-01-05". (That's the external format; internally it is similar to MEDIUMINT UNSIGNED.)
